Mkpọchi - nsogbu na ngwọta

1. Ihe A (3 kg) na-agagharị n'ọsọ nke 8 m/s na ihe B (5 kg) na-agagharị n'ọsọ nke 4 m/s. Ọ bụrụ na nkpọkọ dị n'etiti ihe A na B na-agbanwe agbanwe nke ọma, kedu ihe bụ ọsọ ọsọ nke ihe A na B mgbe ihe ahụ mechara?

A maara:

Mass nke ihe A (m)₁) = 3 kg

Ibu nke ihe B (m)₂) = 5 kg

The ọsọ nke ihe A (v)₁) = 8 ms^-1

Ọsọ nke ihe B (v)₂) = 4 ms^-1

1. Ihe na-agagharị na ọsọ ọsọ nke v = (2i − 1.5j) m/s. Gịnị bụ nnyefe nke ihe ahụ mgbe sekọnd anọ gasịrị?

A maara:

Akụkụ kwụ ọtọ nke ọsọ (v)_x) = 2 m/s

Akụkụ kwụ ọtọ nke ọsọ (v)_y) = 1.5 m/s

Oge etiti oge (t) = sekọnd 4

Nchụpụ nke vector - nsogbu na ngwọta

1. Mmadụ na-aga site na isi A ruo isi B, mita 600 n'ebe ugwu; wee gaa na isi C, mita 400 n'ebe ọdịda anyanwụ; wee gaa na isi D, mita 200 n'ebe ndịda; wee mechaa na isi E, mita 700 n'ebe ọwụwa anyanwụ. Kedu ka ibu nke nnyefe?

Ngwọta:

A maara:

AF = AB - BF = AB - CD = 600 - 200 = 400 m

EF = DE – DF = DE – BC = 700 – 400 = 300 m

Ịgbakwunye vektọ site na iji ihe mejupụtara - nsogbu na ngwọta

1. Vektọ atọ dịka egosiri na eserese dị n'okpuru.

V₁ = 30

V₂ = 30

V₃ = 40

Gịnị bụ ihe si na ya pụta? vektọ.

A maara:

V₁ = 30, nkuku dị n'etiti V₁ na x axis = 30^o

Eserese nke mmegharị ahịrị - nsogbu na ngwọta

1. Eserese anya (kwụ ọtọ) na oge (kwụ ọtọ) dịka egosiri na eserese dị n'okpuru. Ihe dị n'oche nke egosiri site na nọmba…

Ngwọta:

Nọmba nke atọ, nke e gosiri site n'ahịrị kwụ ọtọ.

Ọsọ nkezi - nsogbu na ngwọta

1. Mmadụ na-agba gburugburu akụkụ anọ nwere ogologo nke mita 400 na obosara nke mita 100, ugboro iri na abụọ n'ime otu awa. Kedu ihe bụ nkezi ọsọ na nkezi ọsọ?

A maara:

Ogologo akụkụ anọ = mita 400

Obosara nke akụkụ anọ = mita 100

Gburugburu akụkụ anọ ahụ = (mita 2 x 400) + (mita 2 x 100) = mita 800 + mita 200 = mita 1000

Ogologo = mita 12 x 1000 = mita 12,000 = kilomita 12

Ụkpụrụ ojii - nsogbu na ngwọta

1. Mmiri gram 200 na okpomọkụ 30°C gwakọtara ya na mmiri gram 100 na okpomọkụ 90°C. kpọmkwem ọkụ mmiri = 1 kalori^-1° C^-1Chọpụta okpomọkụ ikpeazụ nke ngwakọta ahụ!

A maara:

Mass mmiri 2 (m₁) = gram 200

Okpomọkụ mmiri 1 (T)₁) = 30^oC

Mmiri dị n'ọbara 2 (m₂) = gram 100

Ihe Dynamics iri eji eriri jikọọ n'elu igwe Atwood - Nsogbu na Ngwọta

1. Blọk A na a uka nke kilogram ise, e tinyere ya n'elu oghere kwụ ọtọ dị larịị. Blọk B nwere oke ibu nke kilogram atọ kwụgidere n'otu nsọtụ eriri jikọtara ya na blọk A n'elu pulley. Ọsọ ọsọ n'ihi ike ndọda bụ 10 m/s². Gịnị bụ ọganihu nke blọk abụọ ahụ?

A maara:

Oke nke ngọngọ A (m)_A) = 5 kg

Oke nke ngọngọ B (m)_B) = 3 kg

Ọsọ ọsọ n'ihi ike ndọda (g) = 10 m/s²

Mmegharị okirikiri - nsogbu na ngwọta

1. Ihe dị kilogram iri na-agagharị n'ime okirikiri na ọsọ na-agbanwe agbanwe nke mita anọ na ọkara (4 m/s). Ọ bụrụ na radius nke okirikiri ahụ dị mita 0.5, mgbe ahụ:

1) Ugboro nke okirikiri bụ 4/π Hz

2) Nke osooso centripetal bụ 32 ms^-2

3) Nke ike centripetal bụ 320 N

4) Oge ahụ bụ 4π s.
